Functional Description
The ACT534 consists of eight edge-triggered flip-flops with
individual D-type inputs and 3-STATE complementary out-
puts. The buffered clock and buffered Output Enable are
common to all flip-flops. The eight flip-flops will store the
state of their individual D inputs that meet the setup and
hold times requirements on the LOW-to-HIGH Clock (CP)
transition. With the Output Enable (OE) LOW, the contents
of the eight flip-flops are available at the outputs. When the
OE is HIGH, the outputs go to the high impedance state.
Operation of the OE input does not affect the state of the
flip-flops.
